It is quite possible to learn carving on inline skates. If you were here, I could teach you how. The "bending the skis at hookup" element is replaced by "deform the wheels at hookup". You are not creating enough outside skate pressure. You need to be more 'stacked' above the skate. You need to have countering movements and angulation as well, all with a vertical torso.
It is so easy to carve on inlines. What is missing from it is the offset edges -- inline edges are under foot, ski edges are to each side.
IMO, pumping/entending the outside leg late in the arc is your movement to energize the skate. As per BigE's suggestion- early counter movements to balance and create pressure on the outside skate will go a long way to help with your inline and your skiing.
Harb carvers are without question (IMO) the best ski crossover training tool I have found. I have inlined since the mid nineties with skiing movements as a main focus. This spring I got the carvers and WOW! They are like a truth serum. I love going distance on my five wheels but the carvers are the training tool for skiing simulation.
I like the way you flex the outside leg to release the arc. Continue the tipping movements of that old outside skate into the next arc.
I hope you want MA. If not, sorry. Bolter
